[root@localhost yum.repos.d]# 安装docker
[root@localhost ~]# yum -y install docker-ce#启动服务
[root@localhost ~]# systemctl enable --now docker

/usr/bin/docker配置docker加速器
docker的加速有多种方式：
- docker cn
- 中国科技大学加速器
- 阿里云加速器（需要通过阿里云开发者平台注册帐号，免费使用个人私有的加速器）
[root@localhost ~]# cat /etc/docker/daemon.json
{"registry-mirrors": ["https://k654a2v7.mirror.aliyuncs.com"]
}重启服务
